prophylactic antimicrobial therapy
Preventive administration of antibiotics, antivirals, or antifungals to reduce infection risk in immunocompromised patients.
Full Definition
A therapeutic strategy involving the routine administration of antimicrobial agents to prevent infections in patients with known immunodeficiencies before clinical signs of infection appear. This approach is commonly used in pediatric immunology for patients with severe T-cell deficiencies, neutropenia, or other conditions that predispose to specific infections. The choice of antimicrobial agents depends on the type of immunodeficiency and the most likely pathogens. Prophylactic regimens must be carefully balanced against the risks of antimicrobial resistance and adverse effects. Documentation should clearly distinguish prophylactic from therapeutic antimicrobial use.
Usage
Usage note: Specify 'prophylactic' to distinguish from therapeutic antimicrobial use.
